Frequency
The output frequency is controlled with the FREQuency command. To set the output
frequency to 50 Hz, use:
FREQuency 50
Turning on output voltage at a specified phase angle
The following command sequence will turn the output voltage on at a specified phase angle.
This may be required to measure worst case inrush current.
/* Set up sequence
VOLT 0
Set output voltage to zero
OUTP 1
Close output relay
OUTP:STAR:STAT 1
Enable start phase mode
OUTP:STAR:PHAS 90
Set start phase angle to 90 degrees
OUTP:DROP
Put AC source in infinite drop mode
/* Turn on sequence
VOLT 230
Turn on voltage to 230 V at 90 degrees
Current Limit
To set the RMS current limit use:
CURRent
where
If the load attempts to draw more current than the programmed limit, The AC source is
programmed to turn off its output if the RMS current limit is reached.
Note:
The CURRent command is coupled with the VOLTage:RANGe.This means
that the maximum current limit that can be programmed at a given time
depends on the voltage range setting in which the unit is presently
operating.
